PIN-POINT SHIELD.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed November 19, 1913. Serial No. 801,911.

To all whom it may concern Be it known that I, KONSTANTY WVIsLIN- SKI, a subject of the Czar of Russia, residing in Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in Pin-Point Shields, of which the following is a specification.

This invention relates to shields or protectors for the sharp points of pins and similar devices.

It particularly'relates to a shield for the pointed end of a hat-pin.

The primary object of my invention is to provide a shield of simple construction which may be easily applied to the pointed end of a pin and will automatically interlock therewith and remain so interlocked until manipulated in a particular way, when it may be easily detached.

In carrying out my invention I form a slot in the pointed end of the pin and I provide a shield with a socket adapted to receive such slotted end. Within the shield I arrange a locking lever which is springactuated and has a shoulder which enters the slot in the pin and engages the front wall thereof. Atthe inner end of the socket is arranged a yielding cushion which receives the pointed end of the pin, protects it and tends to force it backward. The rear end of the slot in the pin is beveled or inclined and engages an inclined shoulder on the locking lever. The arrangement is such that when the pin is inserted in the shield the lever automatically enters the slot and locks the pin to the shield so that it cannot be disengaged therefrom unless the shield is forced backward on the pin so as to disengage the lever from the slot and then after the shield is given a partial turn about the axis of the pin the two members may be separated.

In the accompanying drawings, Figure 1 shows a side elevation of a hat-pin and shield embodying my improvements. Fig. 2 is a view on an enlarged scale partly in elevation and partly in section showing a shield made in accordance with my invention applied to the pointed end of a pin. Fig. 3 is a perspective view of the flaring guide at one end of the shield. Fig. 4 is a perspective view of a portion of the shield showing how the locking lever is applied thereto. Fig. 5 shows a transverse section on the line 5-5 of Fig. 2. Fig. 6 is a perspective view of the pointed end of the pin;

lVhile I have shown my invention applied to a hat-pin, it will be understood that it may be applied to pins of various kinds.

In Fig. 1 of the drawings I have shown a hat-pin A provided with a head B which may be of any ornamental character and inasmuch as my shield is absolutely secure and certain, the head may be jeweled or made of precious material of any kind. C indicates the shield made in accordance with my invention which serves to cover and protect the pointed end of the pin and also to prevent the pin from being detached from the hat or other article to which it is attached.

I have shown the shield made in several parts, but the details of construction shown are not essential. Preferably however I employ a metallic tubular portion E which is provided with parallel flanges e separated a suflicient distance to receive a locking lever D which is pivoted to the flanges at d. This lever is formed with a shoulder m and with another inclined shoulder at. The lever has a spring arm which normally rests on a pin 6 attached to the flanges e. The inner or rear end of the tube E receives a flaring or trumpet shaped guide C and the outer end of the tube E receives a button or head C, which may be made of precious metal or of any other desired material and may be of any desired shape or construction. The shield thus constructed provides a socket for the pointed end of the pin and at the inner end of the socket is arranged a yielding cushion c which is preferably made of rubber. When the pin A enters the socket it will engage the cushion and the pointed end of the pin will not be blunted or injured, and furthermore said spring cushion serves another purpose which will be hereinafter described.

The pin A is pointed at a and is provided with a slot a, the front wall of whichis preferably straight, while the rear wall is inclined or doubly inclined, as shown at a When the pin is inserted in the socket and pressed inward against the cushion a the locking lever D will not engage in the slot a unless the pin is inserted to the proper extent. If inserted too far it will not thus engage, but by relieving the pressure on the pin and allowing the cushion c to act, the

pin will bev moved backward to a sufficient extent to allow the locking lever to auto matically engage in the slot of the needle in the manner indicated in Fig 2. en

thus engaged the .shield and the pin are firmly connected, and if ittbe attempted to separate the shield from the needle it cannot be done because the shoulder m of the looking lever firmly engages the front wall of the slot in the needle. If, however, the needle be forced inward, the inclined wall M,

which engages the inclined shoulder cl, will depress the lever causing the locking shoulders' to leave the slot 00 and then if the pin be first given a partial turn it may be easily withdrawn. t

, Itwill be observed that there are no projecting catches which it isnecessary to opcrate in order to cause the shield to be engaged with or disengaged from the pin. The locking devices are all housed or contained within the interior of the shield.

After the pin is inserted through the hat it is only necessary to place the shield over the pointed end of the pin, move it longitudinally on the pin until the point thereof engages the cushion and then by slightly relieving the pressure and giving a partial turn to the shield orto the pin the locking lever will automatically engage in the slot 00. This operation isa very quick and natural one as is also the operation of'detaching the shield from the pin, but said operation is such that it is not aptto occur accidentally but must be performed designedly.

I claim as my invention:

L. The combination of a pointed pin formed with a slot in itspointed end having a straight front wall and a rear wall provided with inclined surface and a shield having a spring pressed locking lever formed with a straight shoulder adapted to enter the slot and engagethe front wall thereof and another shoulder adapted to engage the inclined rear wall of said slot, the arrangement being such that when said pin is pushed into the shield one of the shoulders of said locking lever engages the front wall of the slot and prevents the withdrawal of the pin from the shield while the other shoulder of said locking lever is adaptedftoso engage the inclined rear wall of the slot of the pin that when the pin is pushed inwardly to a .suflicient extent the locking lever wit-lidrawnfrom engagement with the slot and permits the pin to be turned in the shield to remove the slot from engaging position with the locking lever whereby the pin may then be withdrawn endwise from the shield. I

The combination of a pointed pin having a slot in its pointed portion, a. shield receiving the pointed end of the pin, provided with a locking lever having a shoulder adapted to engage the front wall of the slot and when so engaged preventing the 6011165 of this patent iiiay he obtained f withdrawal of the shield from the pin and another shoulder having an inclined surface engaging the rear wall of the slot, the arrangement being such that when the shoulders of said lever are within the slot endwise withdrawal of the pin is prevented but when the pin is pushed inward the shoulders are moved out of the slot and permit the pin to be turned to withdraw the shoulders from engaging position with the slot to allow the pin to be withdrawn endwise from the shield.

3. The combination of a pointed pin formed with a slot in its pointed end having a locking front wall, a shield which receives the pin, a cushion in the front portion of the shield which is engaged by the pin and permits the pin to be pushed forward but which when the pin is released moves the pin rearward to a small extent, and a locking lever carried by the shield having a shoulder engaging the front wall of the slot and preventing when so engaged the withdrawal of the pin from the shield and another shoulder engaging the rear wall of the slot, said shoulder and rear wall being relatively inclined whereby when the pin is moved inward sufliciently into on gagement with the cushion the lever is moved from locking engagement with the slotted pin and permits the pin to be turned out of engaging position to allow the endwise withdrawal of the pin. e

4. The combination of a pointed pin formed with a slot in its pointed end, a shield receiving the pointed portion of the pin, a cushion in the frontend of the shield which receives the pointed end of the pin, allows it to be pushed inward but which when the pin is released moves the latter outward and a locking lever carried by said shield having a shoulder adapted to engage the front wall of the slot and to prevent the withdrawal of the shield from the pin when so engaged and another shoulder adapted to engage the rear wall of the slot, said last mentioned shoulder and rear wall being provided with an inclined surface whereby when the pin is moved inward and the cushion is compressed the locking lever is moved out of engagement with the slotted pin and permits said 'pin to be turned within the shield to move the locking lever out of engaging position with the slot to allow the pin to be withdrawn from the shield.

In testimony whereof, I have hereunto subscribed my name.
